Mark up attachments
When you’re writing a message and add an image or PDF document, you can use Markup to write or draw on the attachment, or to add shapes or a signature to it.
Move the pointer over the image or PDF you added to your message, click the Action pop-up menu
that appears in the upper-right corner of the attachment, then choose Markup. Or simply force click the image.If you don’t see the pop-up menu, you may need to enable Markup. Choose Apple menu > System Preferences, click Extensions, click Actions, then select the Markup checkbox.
Use the tools to mark up the attachment.
You can adjust how much of the attachment is shown at any time: move the pointer near the edges, then drag the blue handles.
To duplicate any shape, text, or signature, press and hold the Option key while you drag an item; use the yellow guides to align the items.
